Switchable Units 

Definition

In the context of the Switch Framework, development objects can be of two types: switchable and non-switchable. Both types can be assigned to switches. The behavior of switchable objects in the system depends on the switch settings.

Types of Switchable Units

Below is the list of switchable units:

●      Packages

You can switch the following repository objects by assigning them to a package:

○       Append Structures, Includes, and Customizing Includes for structures in the ABAP Dictionary

The switches affect only SI_ and CI_ includes. The normal dictionary includes are not affected by switches.

○       Append Search Helps for search helps in the ABAP Dictionary

○       Secondary indexes for database tables in the ABAP Dictionary

○       Fixed Value Appends for domains in the ABAP Dictionary

○       Business Configuration Sets of the Customizing

○       Enhancement Implementations of the Enhancement Technologies of the Enhancement Framework.

●      Screen fields

You can assign a switch to each screen fields when you define it in the Screen Painter. A screen field can be used only when the switch is switched on. By assigning a switch to a screen field, you also assign the corresponding FIELD statements of the screen flow logic. The FIELD statements are only taken into account if the switch is switched on.

When you define a screen field, you should specify whether the corresponding screen elements are to be hidden when the switch is switched on. In this way, you can replace existing screen fields with others.

The program SFW_FIND_SWITCHED_ELEMENTS can be used to search switched UI elements by business function. Its scope are the UI elements assigned in Screen Painter.

●      Calling modules

You can link the MODULE statement of the screen flow logic to a switch directly through the SWITCH addition. Such a MODULE statement is only taken into account if the switch is switched on.

●      Function codes

You can assign a switch to a function code when defining the function code in the Menu Painter.

●      Maintenance views and view clusters

You can assign a switch to any field of a maintenance view when you define the view in the ABAP Dictionary. All fields that you want to switch need to be part of the maintenance view. No appends are used for the switchable parts of a maintenance view.

The same applies to view clusters. You can specify one switch for each view to control its visibility. All views that you want to switch need to be part of the view cluster.

●      Nodes of an IMG structure

You can assign a switch to each node of an IMG structure in the IMG Structure Maintenance. An IMG structure node is displayed only when the switch is switched on.

●      Nodes of an area menu

You can assign a switch to each node of an area menu in the Area Menu Maintenance. An Area Menu node is displayed only when the switch is switched on.
